Accessory Applications:

• The excavator has been primarily designed for moving earth with a bucket.
• For use as a grapple or for other object handling, contact Daewoo. Lifting- work applications (unless restricted or prohibited by local regulations) are permitted in approved lift configuration, to rated capacity only, with no sideloading.
• DO NOT use the machine for activities for which it was not intended.
• DO NOT use the bucket for lifting work, unless lift slings are used in the approved configuration.
• Use of an accessory hydraulic hammer (breaker), work in rough terrain, demolition applications or other hazardous operation may require installation of additional protective structures to safeguard the operator.
• Refer to Section 3 in the Shop Manual for additional information on Falling Object Protective Structures (F.O.P.S.) and other reinforcement systems.

Lifting Capacity Rating Configuration:

• Lifting capacity ratings that are printed at the end of this safety section are based on the machine being level, on a firm supporting surface, with hooks and slings attached in approved configuration.
• Loads must be balanced and supported evenly.
• Use taglines to keep the load steady if wind conditions and large surface area are a problem.
• Work crew hand signals, individual tasks and safe procedures should all be universally understood before the lift is made.

IMPORTANT:

• Before using the excavator to make lifts check municipal and regional regulations or statutes that could apply.
• Governing ordinances may require that all heavy lifting be done with single purpose equipment specifically designed for making lifts, or other local restrictions may apply.
• Making heavy lifts with a general purpose excavator that can be used for digging, loading, grading or other work may be expressly forbidden by a regional injunction or other legal prohibition.
• Always follow all of the other instructions, guidelines and restrictions for Safe Lifting in the Operation and Maintenance and Shop Manuals.

Locations of Safety Labels:

• Always keep these labels clean.
• If they are lost or damaged, replace them with a new label. It is the responsibility of the equipment owner and crew to provide essential safety information in the immediate vicinity of hazards.
• Safety labels may be available in languages other than English, or labels providing a warning for other hazards than those that follow may be available.
• Contact your Daewoo distributor to find out what labels are available.
